raspberries. Entrance is made near the top of the shoot in a leaf axil, 
which was probably in the top bud at the time the egg was laid, and from 
this entrance the larva works its way in an irregular course down 
through the pith until it comes within a few inches of the ground, when 
it girdles the canes as represented in the extract. As soon as the top 
wilts the maggot continues its course downward through the pith. 
Careful search was made in neighboring berry patches and in our 
own at the college, but nothing more of the kind was found. Not so 
much would have been thought of this one local injury had not there 
come a letter from Costello, Pa., about two weeks later, describing the 
work and maggot exactly at that place. It was stated that the injury 
was considerable in the locality. This made me think that perhaps the 
species is more widespread than thought at first. Every effort was 
made to rear the maggots which I had, and I was successful for some 
time by transferring them every few days to fresh shoots. The last 
maggot reached a length of ll n in , when it died. 
ADIMONIA CAVICOLLIS ON CHERRY FOLIAGE. 
A, correspondent at Bellaire, Mich., sent me specimens of this Chrys- 
omelid the latter part of May, saying that they were causing damage 
to cherry trees of that locality. On investigating the life history of 
the species I find that it is reported by Packard in Forest Insects under 
Galeruca sanguinea as found abundant in New Hampshire on wild 
cherry. 
Like so many insects that we find each year, the Adimonia has in 
some way found that a cultivated plant closely related to its old food 
plant is preferable, and is making the most of the newly found plant. 
The beetle is spoken of by Mr. Schwarz (Insect Life, vol. vi, p. 94) as 
being a common northern species, and we may possibly yet find it quite 
a serious pest. 
In response to my inquiry my correspondent wrote that there were 
wild cherry trees not far away, with a few of the beetles on them. 
Larvae received July 10 were about 5 mm long, not very broad, and 
tapering posteriorly. Head, legs, prouotum, and terminal plate black 
in all the specimens, except one which was larger, and these parts in 
that one are reddish brown. On the dorsum of each segment are two 
transverse rectangular parallel dark spots, with two or more smaller 
ones on the sides at the end of the large ones, and beneath these is a 
longitudinal block on each segment. The venter of each abdominal 
segment is marked with five dark brown spots, the central one being 
largest. 
NOTOXUS ANCHORA EATING CHERRIES. 
In connection with the Adimonia this species of Notoxus might be 
mentioned. It was reported from northern Michigan as collecting in 
large numbers on nearly ripe cherries and eating the contents from
